Tempi di risposta del Display

I tempi di risposta del display mostrano quanto sia veloce lo schermo a cambaire da un colore all'altro. Tempi di risposta lenti poccono creare sovrapposizioni negloi oggetti in movimento. Specialmente i giocatori patiti del 3D dovrebbero usare uno schermo con rempi di risposta bassi.
       Tempi di risposta dal Nero al Bianco
36 ms ... rise ↗ and fall ↘ combined↗ 19.6 ms Incremento
↘ 16.4 ms Calo
Lo schermo mostra tempi di risposta lenti nei nostri tests e sarà insoddisfacente per i gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 90 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (26.1 ms).
       Tempo di risposta dal 50% Grigio all'80% Grigio
52.4 ms ... rise ↗ and fall ↘ combined↗ 24.8 ms Incremento
↘ 27.6 ms Calo
Lo schermo mostra tempi di risposta lenti nei nostri tests e sarà insoddisfacente per i gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 87 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (41.7 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 10570 (minimum: 43 - maximum: 588200) Hz was measured.

HP ProBook 450 G5
HP ProBook 450 G5

Il ProBook 450 G5 è un economico portatile da 15.6" del segmento entry-level business con buone prestazioni.

Di grande importanza per i portatili da ufficio sono ovviamente la tastiera, che in questo caso ha un buon feedback. Tuttavia, ci hanno infastidito i piccoli tasti direzionali. Il touchpad non ha evidenti pecche, grazie alla superficie in vetro e al driver Microsoft Precision. Il display matto IPS ha un contrasto superiore a 1000:1, non si nota PWM ed effetto bleeding della retroilluminazione e la luminosità è di 250 cd/m². Sebbene la rappresentazione dei colori sia pessima, questo può essere messo da parte considerando il prezzo e la natura del pannello. Nonostante le decenti prestazioni CPU, il ProBook resta silenzioso. Le porte sono ammirevoli rispetto alla concorrenza. La porta VGA è importante soprattutto per gli studenti, e c'è anche uno slot full-size SD card. Positive anche le casse, che sebbene non eccezionali, non sono nemmeno pessime, cosa che non accade sempre con i portatili da ufficio. Infine, da notare la possibilità di upgrade, grazie ai due slots RAM, allo slot M.2 e SATA per drives da 2.5", non c'è null'altro da desiderare.

La principale critica riguarda lo chassis: il ProBook potrebbe essere più compatto, la base intorno al display è troppo grande per gli standards attuali. La qualità di costruzione non è il top, specialmente nella parte frontale del case. Il posizionamento delle porte non è ideale e dovrebbe essere migliorato in futuro. A destra le porte sono troppo vicine tra loro. La possibilità di upgrade è buona, il sistema di raffreddamento però non è facile da raggiungere e pulire. La garanzia offerta è troppo breve considerando prezzo e fascia di mercato.

Raccomandabile: il ProBook 450 G5 ha sicuramente un bilancio in positivo.

In conclusione, il ProBook 450 G5 merita una raccomandazione. Si offre come buona alternativa al ThinkPad E580, specialmente se non ci interessa in particolare la GPU e le applicazioni pesanti.

Nota: si tratta di una recensione breve, con alcune sezioni non tradotte, per la versione integrale in inglese guardate qui.
